我不知道为什么我的json对象返回undefined。我在JSON工具中没有看到任何语法上的错误，但我觉得我的构造方式一定有问题。
我想开始制作僵尸游戏，但对我而言，第一步是了解如何将我创建的数据传递到前端。这是我一直希望为类实现ajax的地方，但是我的控制台发送了一个错误：“undefined”
$(document).ready(function(){
$.ajax({
url: 'dummy_json.json',
data : { load : true},
type: 'GET',
dataType: 'json',
timeout: 1000,
error: function(jqXHR, textStatus, errorThrown){
console.log("HOLY SHIT ZOMBIES!");
console.log(textStatus + " is " + errorThrown);
},
success: function(data){
$("body").append(data); // really basic append, more to come.
}
});
});
以下是dummy_json.json文件的内容，其中包含我手写的僵尸任务数据。我想从头开始这样做，这样我就可以很好地学习json。最后，我将编写从db中提取此内容并将其转换为json以供视图使用的php：

答案 0 :(得分：2)
这是无效的JSON。你需要将整个东西包在方括号中，使其成为一个数组：
[ { id : 0, ... },
{ id: 1, ... },
...
]
注意，要检查JSON是否有效，有很多可以提供帮助的在线工具（例如JSONLint）。 （你会看到那里有效的JSON技术上要求将密钥（id等）包装在双引号中。）
